Jamie Grier created FLINK-4391: ---------------------------------- Summary: Provide support for asynchronous operations over streams Key: FLINK-4391 URL: https://issues.apache.org/jira/browse/FLINK-4391 Project: Flink Issue Type: New Feature Components: DataStream API Reporter: Jamie Grier
Many Flink users need to do asynchronous processing driven by data from a DataStream. The classic example would be joining against an external database in order to enrich a stream with extra information. It would be nice to add general support for this type of operation in the Flink API. Ideally this could simply take the form of a new operator that manages async operations, keeps so many of them in flight, and then emits results to downstream operators as the async operations complete. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
